Pseudo Code for Creating a Table

Objective

The purpose of this pseudo code is to outline the steps required to create a database table with specified columns and data types.

Assumptions

• The database connection is already established.
• There is a designated name for the table.
• Columns include data types and constraints.

Pseudo Code Structure

1. Define Table Parameters

DEFINE table_name AS STRING
DEFINE columns AS LIST OF COLUMN_DEFINITIONS

2. Specify Column Definitions

DEFINE COLUMN_DEFINITION AS OBJECT
COLUMN_DEFINITION.name AS STRING
COLUMN_DEFINITION.data_type AS STRING
COLUMN_DEFINITION.constraints AS LIST OF CONSTRAINTS

SET columns TO [
    { name: "id", data_type: "INTEGER", constraints: ["PRIMARY KEY", "AUTOINCREMENT"] },
    { name: "name", data_type: "VARCHAR(100)", constraints: ["NOT NULL"] },
    { name: "date_created", data_type: "DATETIME", constraints: [] },
    { name: "is_active", data_type: "BOOLEAN", constraints: ["DEFAULT TRUE"] }
]

3. Build Create Table SQL Query

DEFINE sql_query AS STRING
SET sql_query TO "CREATE TABLE " + table_name + " ("

FOR EACH column IN columns DO
    sql_query += column.name + " " + column.data_type
    IF column.constraints IS NOT EMPTY THEN
        sql_query += " " + JOIN(column.constraints, " ")
    ENDIF
    IF column IS NOT LAST COLUMN IN columns THEN
        sql_query += ", "
    ENDIF
ENDFOR

sql_query += ");"

4. Execute SQL Query

EXECUTE sql_query ON DATABASE

IF execution SUCCESS THEN
    PRINT "Table " + table_name + " created successfully."
ELSE
    PRINT "Error creating table: " + ERROR_MESSAGE
ENDIF

Summary

The above pseudo code details the steps necessary for creating a database table, including defining the table’s name and its columns, constructing the SQL query dynamically, and executing it against the database. This structured approach aids in maintaining clarity and ensuring systematic execution of the process.
